987,529. DOOR-CHECK. JOHN time Youno, Kingsbury, Ind. Filed Dec. 28, 1910. Serial No. 599,671.

j To all whom it may concern:

Be it known that I, JOHN H. YOUNG, a

citizen of the United States, and a resident of Iungsbur 1n the county of Laporte and 1 State of In iana, have invented a new and Improved Door-Check, of which the following is a full,clear, and exact description.

An object of the invention is to provide a device for closures such as doors, to retam a door in a desired position.

" For the purpose mentioned, use is made of a casing for attachment to a door, a plunger mounted to slide in the casing and adapted to extend therefrom, a pawl for engagement with the plunger to retain the same in theorising, a spring. for moving on end of tachmcnt to one end the plunger outwardly from the casing when the pawl is released from the plunger a resilient pad secured to the bottom out oi the plunger, means for limiting the inward movement of the plunger and a guard plate for attachment to the casing jury to the closure by the p unger.

In a number of door checks now in use,

; the plunger at all times projects outwardly F a distance beyond the lower end of the casing and causes great inconvenience, parl tieularly when a floor covering such as a rug is disposed to lie beneath the path of to prevent in- 2 the door when it is opened or closed, inasmuch as the space between the lower part of a door and the floor 15 not very large and i the plunger repeatedly with the floor covering. Other door checks tend to mar the door or floor when they are operated and it is to overcome these diflii culties and inconveniences that I have provided my device.

In my door check, Iaim to provide a I device that will not mar the closures and floor and in'whieh the plunger will be flush 5 2-2 in Fig. I my door 0 1e view taken on t with the lower end of its casing when the said door check is in inoperative position.

A further object of my device is to pro- .vide a convenient and easy manner of o eratin" the door check to obtain the resu ts for which it is adapted.

Reference is to be had to the accom anying drawings. constituting a part'o this specification, in which similar characters of reference denote corresponding parts in all Q the views and in which- Figure 1 is a perspective view of my device attached to a door; Fig. 2 is a-lon ij tudinal sectional view taken on the line 1; Fig. 3 is a rear elevation of ck, parts being broken away to disclose the underlying structure; Fig. 4 is a perspective view of the guard plate of my door checkI and Fig. 5 is a sectional 0 line 5-5 in Fig. 3.

scrapes and contacts =2 war Referring more articularly to the various views, I

emp oy a casing 10 for atof the door. Mounted to slide in the casing 10 is a lunger stem 12 provided at its n l:-

er en with a laterally extending hand e 13, and at its lower end with a plunger 14, having secured on its lower end a resilient 1 pad 15. Integrally formed on the casing ;l 10, interiorly thereof and disposed between the ends of the casing is a stop lug 16. Exteriorly mounted on flanges 17 on the casing 10 is a pawl 18 havin on one end thereof a lug 19, adapted to t into a notch in tie plunger 14, and the other end of the pawl 8 terminates in a foot handle 20. A sprin 22 is provided for actuating the lunger 1% to move out of the casing when t e pawl is released from the plunger. On the hack of the casing 10, flanges .23 are formed with grooves .24 on both sides of the flanges for receiving a guard plate 2 provided with notches 26 in which the flanges 23 are adapted to fit.

In the operation of my device, when the plunger is within the casing 10 and it is desired to extend the ilunger therefrom, a sli ht pressure of the not on the handle .20, will release the pawl 18 from the plunger 14 and'the spring 22 will move the plunger outwardly from the casing it) to engage the floor and thus retain the door 11 in the desired position. To return the plunger l-l within the casing 10 an upward pull of the plun or stem 12 will move the plunger uply to a position shown in Figs. 2 and i 3, thus reengaging the pawl 18 with the plunger to hold the same and releasing the door so that it can he swung on its hinges in the usual manner. As has been heretofore mentioned, when the plunger is disposed within the casing 10, t ie lower end of the lunger will be flush with the lower end of t e casing and will not project beyond the edge of the said casing unless the pawl 18 is released from the plunger, thus permitting it to move downward and engage the floor.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:-

A door check comprising a casing for at.- tachment to a closure, a plunger stem mounted to-slide in the casing, a plunger mounted on said stem, a pawl mounted on the casing and adapted to engage the said plunger, 0. stop lug integrally formed on the casing between the top and bottom thereof, for limiting the upward movement of the plunger, flanges formed on the buck ol the casing with grooves on both sides of the flanges. a guard plate adapted to lit into the said grooves and engage the said flanges.

WWWWWW of a door 11 with the lower end of the casing flush with the end t t t t a spring in the said casing, for actuating the said plunger when the said pawl is re- 1 leased from the plunger and a resilient pad I secured to the lower end of the plunger.

In testimony whereof I have signed thisspecification in the presence of two subscribing witnesses.
